A couple weeks ago, I noticed a lump on my right wrist. It didn't hurt bad or all the time, but it moved and seemed to change size, so I did some research on the Internets and decided it was probably a ganglion cyst - no big deal, but I decided to do the adult thing and get it looked at.
WebMD specifically says, 'Whether you have symptoms or not, your ganglion cyst can benefit from medical evaluation. Your doctor can be sure that you have a ganglion cyst, keep you from worrying, and help decide on the best treatment plan for you.'
So, I went in yesterday expecting evaluation and a treatment discussion and WHAM!, without warning, my doctor pops it. And I think she enjoyed it. Weirdo.
She (and WedMD) said that back in the day, people used to pop them by smashing them with a Bible. (Ouch.)
